Example 31 with VersionTag

use of org.apache.geode.internal.cache.versions.VersionTag in project geode by apache.

the class PersistentRVVRecoveryDUnitTest method testConflictChecksDuringConcurrentDeltaGIIAndOtherOp.

/**
   * This test creates 2 VMs in a distributed system with a persistent PartitionedRegion and one VM
   * (VM1) puts an entry in region. Second VM (VM2) starts later and does a delta GII. During Delta
   * GII in VM2 a DESTROY operation happens in VM1 and gets propagated to VM2 concurrently with GII.
   * At this point if entry version is greater than the once received from GII then it must not get
   * applied. Which is Bug #45921.
